Charts in helm are expected to be tied to a version. This naming convention is deliberate and should be retained. Operators may be expected to use multiple versions of a chart during rolling deployments, testing etc., and having the name explicitly reference the version should make tracking, debugging, and human error elimination easier.

@f5tsomanchi The names of resources should be validated in a test environment

@recursivelycurious - as said in the above comments,

The RBAC aspects look fine, however, this MR had not been merged yet due to difficulty around a testing environment to run the system tests. They may need to be modified to run the newer charts.

  • Can you please elaborate the modifications needed to run newer charts ?
